This paper describes a high-precision linear optical scanner, combining an averaged optical sensor array with appropriate 10-¿m graduated scales on a measurement-fixed plate and a Vernier sliced ...

Here is a quick look at how contactless potentiometers work, where they are used, and why they are gaining ground.

We report the first experimental results on the linear encoder based on a resonant-tunneling-diode (RTD) and a periodic linear array of carbon-fiber reinforced plastic (CFRP) plates as a scale. By ...
